This set (2 pcs) of Wisefab V2 upper control arms for the BMW E36 & E46 features a rigid design, length adjustment capabilities and sway-bar mount. However, it requires true (one-piece) rear coil overs. OEM style separate springs can’t be used any more. The Wisefab Rear Upper link upgrade kit for an E36/E46 is the perfect suspension upgrade for any drift build!
